Association method and device for signaling plane and user plane inside LTE system

Abstract

The present invention discloses an association method and a device for a signaling plane and a user plane inside an LTE system. The method and the device solve the technical problems in the prior art that due to the presence of different network configuration policies, the assigned user IP addresses of multiple PGWs might be repeated so as to cause the confusing condition due to the fact that the multiple PGWs are assigned to existing user IP addresses according to an assignment result of PGW equipment in the LTE system. Meanwhile, the method and the device also solve the technical problems in the prior art that since an SGi interface is arranged between PGW and the Internet, the execution evaluation degree of data services realized at each network element in the LTE system, such as eNodeB, PGW and the like, cannot be reflected and the deep analysis on the network cannot be realized. The association method for the signaling plane and the user plane inside the LTE system comprises the steps of extracting the tunnel information on the side of an S11 interface through establishing the signaling process of a user plane channel on the S11 interface of the system; extracting the tunnel information on the side of an S1-U interface from all data at the S1-U interface of the LTE system; and associating the signaling process at the S11 interface with user data at the S1-U interface through the tunnel information on the side of the S11 interface and the tunnel information on the side of the S1-U interface.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method and device for associating a signaling plane and a user plane in an LTE system. Background technique [0002] LTE (Long Term Evolution) is a long-term evolution of the UMTS (Universal Mobile Telecommunications System) technical standard formulated by the 3GPP (The 3rd Generation Partnership Project) organization. The LTE system introduced key technologies such as OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multi-Input & Multi-Output), which significantly increased the spectrum efficiency and data transmission rate (20M bandwidth 2X2MIMO in the In the case of 64QAM, the theoretical maximum downlink transmission rate is 201Mbps, and it is about 150Mbps after removing the signaling overhead. However, according to actual networking and terminal capacity limitations, it is generally considered that the downlink peak rate is 100Mbps, and the uplin...

Problems solved by technology

[0006] The embodiment of the present invention provides a method and device for associating the signaling plane and the user plane in the LTE system, which solves the problem that the IP address of the existing user is allocated by the PGW device in the LTE network. Since there are multiple PGWs, according to the network configuration Due to different strategies, the user IP addresses allocated among these multiple PGWs may be duplicated, causing confusing technical problems, and because the SGi interface is the interface between the PGW and the Internet, it cannot reflect the various network elements in the LTE network such as eNodeB and SGW Technical issues that are not deep enough for network analysis, such as the quality of data services
